Bricked Moto G, Don't Know What to do topic

I wanted Lollipop on my Moto G, so I unlocked the bootloader and installed TWRP. I attempted to flash CM12, and it is stuck in a bootloop. I want to go back to stock now, but I can't because my PC won't recognize my phone in fastboot anymore. I'm freaking out here, please help! I feel really stupid and should've waited for the official OTA!
